want to zap a table on sql server
In line with MSDN's topic
have tried

SQLPREPARE(gnhandle,'Delete from vizkeys','')
SQLEXEC(gnhandle)

which doesn't report any error but doensn't delete anything either.

variations like "Delete from vizkeys where realkey<>'.NULL.'" (which should delete all) don't work either.

Whats the secret?
